Answer:
(c) 0.325
Step-by-step explanation:
Given,
The number of bolts = 12,
Numbers of nuts = 10,
Total items = 12 + 10 = 22
Thus, the number of ways of choosing 8 items out of 22 items = C(22,8)
Now, the number of ways of choosing 4 bolts and 4 nuts = C(12, 4) × C(10, 4)
Hence, the probability of getting four bolts and four nuts
Therefore, option (c) is correct.
